Temperature Setting
Pres and release key 6 or 7. When the key is pressed, the display shows the marking
°C.
Now you can set the required temperature. With key 7 the temperature is reduced and with
key 6 the temperature is increased. When the setting is completed, the marking on the
display starts flashing. After eight flashes the new temperature is set, and the display
shows the temperature of the water in the hot water tank.
In versions with installed thermometer, the thermometer will show ambient temperature,
while the display on the heat pump will show the temperature of water in the lower part of
the water heater. This is why the two temperatures will vary.
WARNING:
If the heating pump is operating outside the temperature zone of
operation, the evaporator may freeze. Then, the heating pump switches off, and the display
shows the marking tLo. After switching off the heating pump will remain inoperational until
the evaporator unfreezes.
Legionella Control Programme
Your heat pump features a system for thermal disinfection for legionella prevention. This
system includes a special function for high temperature heating (up to 65
°C) of water in
the hot water tank. The system operates automatically, switching on the high temperature
heating of water every 14 days. When the temperature in the water tank reaches 65
°C, the
high temperature heating is switched off.
High temperature heating can also be activated manually, by pressing the key 2 (ca. 5
seconds). The display alternatively shows the temperature of water in the hot water tank
and marking LEG. When the temperature in the hot water tank reaches 65
°C, the heat
pump is switched to normal operation.
